Off the line....
Hello everybody,
I've got a '97 4X4 7.3 with a mild Superchip and straight-piped exhaust and a 5-speed. Ever since I got the truck it has always seemed kind of sluggish off the line. When I take off the power delivery is smooth but slow until I get above 2k on the tach. Is this normal? Does it just act this way because the powerband is a little higher? If this is normal I'm OK with it, I just want to make sure there is nothing wrong with it. It just seems that when I mash the go-pedal to the floor it loads up as slowly as if I was at half-throttle. Thanks in advance for any info!

my truck has plenty of torque from about 1400 rpms all the way through the rpm range... it's slow till it gets to that magical 1400 rpm range but after that it rockets... idk it might be cause of my intake?? i know that normally a more open intake will cause a lower torque band

Yeah, alot of how the truck takes off has to do with what gears you have too. I have 4.10s and it will throw you back pretty good when all 8 injectors are working, lol.

If you haven't already you may want to get a Tymer intake or do the 6637 kwik filter. It may need more air. I have the 4:10's also. I am not sure if these trucks are sluggish with the 3:55 gears.

I think the 4.10 gears must make a pretty big difference. I have friends with chipped SD's (everything else stock) and 3.73's, and their trucks don't feel nearly as fast as my '96 with 4.10's. Mine will burn rubber with just a blip of the throttle and there's won't burn rubber just by hitting the throttle. Adding the IC didn't seem to hurt the throttle response at all. I'm sure the heavy torque converter helps, too. It pulls pretty good from rpm in the low teens but does gain as it goes over 2000.
I drive 6ohs quite a bit at work, and their throttle response is terrible. Once they get going it's good, but you hit the gas and then wait.
